Introduction

With Fedora 25 and later, NVIDIA Optimus devices are automatically detected.

This Howto is a subset of the main documentation, please read the NVIDIA Howto first.

Known limitation

Please note that NVIDIA currently only support "outputsource" and not "offloadsink". It means that you cannot disable the dGPU (nvidia). The current workaround is to reboot onto the free Software version using an alternative boot option menu.

Proprietary/FLOSS switch

At this time, this can be done by manually removing "rd.driver.blacklist=nouveau modprobe.blacklist=nouveau" from the grub2 cmdline. The plan is to have a grub2 menu to have the choice. Please see Bugzilla [RFE] Switcher for Xorg nvidia/FOSS config
